PUNCHING AND SHEARING MACHINE.

SPECIFICATION forming part of Letters Patent No. 614,716, dated November22, 1898. Application led April 22, 1898. Serial No. 678,492. (Nomodel.)

To alli/17mm it may concern.-

Be it known that I, OLE OLsEN HATLELI, a citizen of the United States,residing at Fosston, in the county of Polk and State of Minnesota, haveinvented certain new and useful Improvements in Punching and ShearingMachines 5 and I do declare the following to be a full, clear, and exactdescription of the invention, such as will ,enable others skilled in theart to which it a'ppertains to make and use the same, reference beinghad to the accompanying drawings, and to the letters of reference markedthereon,which form a part of this specification. p

This invention relates to certain new and useful. improvements inpunching and shearing machines, and especially to a device of thischaracter in which a series of differentsized punches are utilized,whichare arranged in a circular series on a rotary disk, in connection withwhich is a die, also rotatable on a suitable standard, means beingprovided whereby the die and the disk carrying the punches may berotated, the power which is applied to the punch being through atogglejoint.

Another part of the invention resides in the provision of means fordrawing the punch out of the aperture which it has made, said meansconsisting of a pair of jaws which engage over the head of the punch andwithdraw the latter when pressure is removed and theoperating-handlethrown back to its starting position.

To these ends and to such others as the invention may pertain the sameconsists, further, in the novel construction, combination, and theadaptation of parts, as will be hereinafter more fully described andthen specitically defined in the appended claims.

My invention is clearly illustrated in the accompanying drawings, which,with the letters of reference marked thereon, form a part of thisapplication, and in which drawings similar letters of reference indicatelike parts throughout both views, in which- Figure l is a perspectiveview of my irnproved punching-machine; and Fig. 2 is acentral,longitudinal,and vertical section through the punching-machine,showing the relative arrangement of parts.

Reference now being had to the details of the drawings by letter, A Adesignate the legs supporting the frame B. This frame B is made up oftwo complemental sections held together by means of bolts A', B', andB2. The forward ends of these jaws are mounted on a bolt C, which bolthas screw-threaded connection with the block D,which is mounted on thelegs E. J ournaled on the said bolt B2 is the lever F,which has a recessF at one end near its pivotal portion,which recess is adapted to receivethe jaws G. The opposite end of the said lever has segmentteeth l-I,which are adapted to mesh with the teeth of the segment K, which segmentis pivoted on the bolt B'. The opposite end of the said segment hasrecesses G', in which an operating-lever G2 is adapted to engage when itis desired to operate the levers.

Loosely journaled on the shank of the bolt C is the disk L, having acircular series of apertures L therein, each aperture in which se- :riesis adapted to receive a punch N. These punches N have heads N' and areguided vertically by means of slots n, engaging with screws n', locatedopposite each aperture in the cirurnference of the said disk. A spring Mis mounted on the shaft of each punch and is provided to assist eachpunch in returning to its starting position after pressure has beenapplied to the same in the act of punching a hole through a piece ofmetal. Loosely mounted also on the shank of the bolt O is the diskQ,which has pins Q', adapted to engage with the perforated disk L, sothat the two disks will move together in unison. This disk Q has aseries of apertures q, adapted to allow the end of the punch to passtherein as it is depressed by the lever above. Pivoted on a bracket R onthe circmference of the said disk Q is the lever S, the inner end ofwhich is adapted to engage in the various depressions T about thecircumference of the said disk for the purpose of causing the latter torotate upon its axis when it is desired to bring one or another of thepunches under the levers provided to force the punch through the metal,as will be readily understood.

lt will be noted that the jaws which are pivoted to the end of the leverF are of such a shape as to allow the head of any one of IOC) thepunches to freely pass through the same, and as a particular punch comeswithin the jaws and the lever is depressed on the return movement of thelever to its starting position the jaws will engage with the head of thepunch and withdraw thesame from the aperture that it has made.

Mounted on a recessed shoulder, one on either side of the said lever, isa blade F4, disposed at an angle, as shown, and is provided to form ashear. The walls of the frame B are provided with elongated apertures"B, which register with an aperture in the lever F, ad jacent to theedges of the cutting-knives F4, whereby pieces of metal may be severedby placing the same in the apertures and causing pressure to be appliedto the operating-lever. V

I am aware that it is common in the art to construct punching-machinesin which toggle-lever joints are utilized; also, punchingmachines inwhich shear-blades are employed. Hence I make no claim for suchconstruction.

Having thus described my invention, what I claim to be new, and desireto secure by Letters Patent, is-

1. A punchingmachine, consisting of a framework made up of twocomplemental sections, segment-levers pivoted between the same, theadjacent ends of which mesh with each other, an operating-handleconnected with one of the said levers, combined with a series of punchesmounted in a rotary disk,

and adapted to be operated by one of the seg- 3 5 ment-levers, as shownand described.

2. In a punching-machine, the framework made up of complementalsections, the segment-levers pivoted between the same and having theiradjacent meeting edges intermeshing,the operating-handle connected withone of the levers, combined with a disk earrying a series of punches inapertures theroin, adapted to rotate underneath the end of one of thesaid levers, and the jaws pivoted to the lever under which the punchestravel, said jaws being adapted to depress and withdraw the punch, asset forth.

In apunching-machine,thelevers mounted as described, the jaws pivoted toone of the said levers, combined with a rotary disk carrying a circularseries of headed punches, adapted to travel through the said jaws as thedisk is rotated, and the die underneath the said disk, as set forth.

4f. In a punching-machine, the levers as described, the jaws pivoted toone of the same, the rotary disk having a circular series of headedpunches, which are spring-actuated, the rotary die adapted to move withthe disk carrying the punches, and an operating-lever adapted to rotatethe said die, as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
